Why is my Trane Pivot BAYSTAT814 Thermostat heat pump not turning on?
- MMrs. Nicole Pena MDAug 6, 2025
The heat pump might not be turning on because the outdoor temperature is below the compressor lockout temperature setting. If desired, you can adjust the compressor lockout temperature setting. Also, check if the system mode is set to Emergency Heat. The outdoor unit may require service, so check/repair the outdoor temperature sensor or wiring.
